Per packet, or per queue?  If you're asking per queue, at least on egress, it would depend on configuration and actual usage as the 3750X can have both per port/queue dedicated buffers and use a share common buffer pool.

Re: 3750X Buffer Size

Hi Joseph,

Thanks for providing your response.

I am after per port (or you can say per packet)? I have a requirement to connect a iSCSI storage which requires atleast 512K of buffer size, as spec'ed by the storage vendor, kinda struggling on if 3750X is suitable or not?

Per queue or shared pool, I am not very concerned as long as we can allocate big buffer size on the port connecting to storage deivice!

Many thanks
